If you'll give me 9:1 odds on this summer being, say, the hottest summer in the US in a century, I'll take it!
According to NOAA, 4 of the years from 1980 to 1997 were the hottest years so far of the century. So this summer has a 1/5 - 1/4 chance of being the hottest year of the century.
As we did last year, use this thread to make predictions for the next year and next decade, with probabilities attached when practical.
Happy New Year, Less Wrong!
